92-year-old man's physical exam

A doctor gave a 92-year-old man a physical exam. A few days later he happened to notice the man walking down the street with his arm around a gorgeous young woman and grinning from ear to ear.

The next time he encountered the man, the doctor said, "You are really doing great, aren't you?"

"Just doing what you said, Doc," the man agreed. "You said, 'Get a hot mamma and be cheerful.'"

"I didn't say that," replied the doctor. "I said you got a heart murmur. And be careful."
